In The Beginning

"Now, how did we get into building rockets? It didn't take very long, because, if you want to be in the transportation business, you need a vehicle. The first thing we did was to do a study of all the vehicles made in the world. We looked especially at U.S. vehicles, and you very rapidly come to find out that every U.S. vehicle is either a missile or derived from a military missile. What that means is that it is a vehicle that was optimized to deliver the maximum pounds of warhead, the maximum distance with a maximum accuracy to the maximum number of Russian missile silos.

That has about as much to do with commercial package delivery business as an Indy 500 race car has to do with what you want to drive out of your driveway every morning and park in the garage next to your office - not much. Indeed, the analogy that we use is, if Federal Express tried to stay in business delivering their packages every day with F-16 fighter planes and if what pulled up in front of your house every morning at 10:30 was a Lamborghini, Fred Smith and Federal Express would be out of business in about 3-1/2 days.
